Isabel Sayago received her Ph.D. in chemistry from the Complutense University of Madrid in 1993. From 2001 on, she been working as a researcher of Sensors Group at the Spanish National Research Council (CSIC) in Madrid. She has published over 70 papers in international scientific journals, getting about 1000 citations. She regularly collaborates as a referee for different SCI journals.
She has participated in more than 25 research projects related to the development of sensor prototypes (resistive and gravimetric types) for gas and/or vapour detection. The sensor prototypes developed have the following applications: Environmental monitoring (air, water, soil), process and quality control (food, beverages etc.), civil security (biological and chemical warfare agents) and health (diseases).
Her researching activity is focused on the design and development of chemical sensors as resistive, SAW and Love-wave sensors and their applications as gas sensors. Nowadays, she is interested in the research and development of semiconductor nanostructures as nanowires, nanofibres and nanotubes due to their potential application in the gas sensors field. She is also interested in the research of new nanomaterials such as carbon nanotubes, graphene or composites. These nanostructures materials are interesting candidates to be the new generation of devices with superior performance to conventional gas sensors.
